449691 divided by 16 
Let's see how many times 16 fits into 449691.

Advancing to step 1:
The number 16 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 16

Moving on to step 2:
If we divide 44 by 16, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 32 away from 44, we end up with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 16

On to step 3:
129 divided by 16 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 128 from 129 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 16

On to step 4:
The number 16 fits into 16 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 281.0
Subtract 16 from 16 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 16

Advancing to step 5:
The number 16 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 2810.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 16

Going ahead to step 6:
When dividing 91 by 16, we get 5 with a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 28105.0
If we subtract 80 from 91, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
16 goes into 110 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 28105.6
If we subtract 96 from 110, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
16 can be fit into 140 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 28105.68
The remainder is 12 after subtracting 128 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 16, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 28105.687
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
16 goes into 80 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 28105.6875
If we take 80 away from 80, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 16 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28105.6875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
When dividing 0 by 16, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28105.6875
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 28105.6875, with a leftover of 0.0.
